Upstream source description

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, the webroot admin.php multisite administration page is enabled without an authentication check, reads database configuration from sqlconf.php, and connects to each configured site database. An unauthenticated network actor can obtain site identifiers, database names, site names, exact OpenEMR versions and patch levels, pending upgrade status, and direct login and patient-portal links. This issue is fixed in version 8.3.0.
